feat(orders): maker order recovery

[onur-ozkan]

Fixes a bug where maker orders would get removed if swaps failed during the early negotiation phase. Before this change, when someone tried to take your order, the order would get immediately deleted from the orderbook. Which means, because of some unrelated issues (mostly coming from flaky taker peers) you would have to manually recreate it everytime.

The fix adds an order "locking" mechanism instead of immediate deletion. When a swap starts, the maker order gets moved to a locked state where it's temporarily hidden from the orderbook but not actually deleted entirely. If the swap completes successfully, the order gets permanently removed as expected. But if the swap fails or gets aborted, the order automatically gets recovered and put back in the orderbook with a fresh time state, so it shows up for other traders in the network again.

Feature is covered up with test_maker_order_recovery_on_tpu test with 3 nodes (Bob, Alice and Onur) and it's passing as expected.

cc @KomodoPlatform/qa for GUI testing: Please test taking an order, aborting the swap from the taker side and then checking if that order gets recovered by viewing it from a 3rd node.

i call setprice every ~10 minutes... it cancels old order and places a new one with new price and maybe new volume
what happens in this scenario? will i end up having 2 orders instead of one?

Nothing has changed in that regard, you can still do that.

I would like to add that this fix is done only for TPU which @cipig doesn't use yet. @cipig You will need to check if it works in a right way or not when testing TPU.
